Love the effects but bugs prevent me from actually using the app – GlitchCam - Video Effects Review

I’ve had this for 2 days now and so far, I love the variety of effects, glitches, and filters. They’re all super unique and exactly what I needed. However, since the moment I got it, I noticed it’s slow to load when I select a video to work on, especially if it’s long. Despite that, I’ve still been able to do what I want until just now- every video I click stays on 0% during the “Processing” pop up. I seriously had made up my mind that I wasn’t gonna cancel the trial and buy it but I can’t anymore if my videos won’t upload...please help.
